Asphalt Institute Vacuum Viscometers are used to measure highly viscous materials such as bitumen, also known as asphalt cement. A minimum sample size of 3ml and a bath depth of 7in (180mm) are required for testing. The elapsed time for a fixed volume of liquid to be drawn through the capillary tube is multiplied by a constant to determine absolute viscosity. Capillary is graduated and a Certificate of Calibration is included with each Viscometer. The 2in (51mm) Viscometer Neoprene Holder is required for operation to secure the viscometers and can be purchased separately. A Constant Temperature Viscosity Bath is also available separately.
The Asphalt Institute Vacuum Viscometers come in five models of varying sizes and ranges of viscosity. Each model measures viscosity at 140°F (60°C).
